SPECIFICATION forming part of Letters Patent No. 529,584, dated November20, 1894.

Application filed February 13, 1894. Serial No. 0 4- (N m To all whom itmay concern:

Be it known that I, FREDERICK BOOTH, of Concord, in the county ofMerrimac and State of New Hampshire, have invented a new and ImprovedSiphon-Valve, of which the following is a full, clear, and exactdescription.

The invention relates to water tanks for flushiu g water closets,urinals, &c., and its object is to provide a new and improved siphonvalve, which is simple and durable in construction, very effective andnoiseless in op: eration, and arranged to automatically drain the tankwhenever the valve is pulled, at the same time using the discharge pipefor an overflow pipe.

The invention consists principally of a valve body fitted to slide onthe fixed outlet pipe, and formed at its lower end with inlet openingsfor the water and at its upper end with a vent extending downwardoutside of the valve body to within a short distance of the bottom ofthe tank.

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafter described and thenpointed out in the claim.

Reference is to be had to the accompanying drawing,forming a part ofthis specification, in which the figure is a sectional side elevation ofthe improvement.

The tank A on which the siphon valve is employed is provided with anoutlet pipe B,

extending at its upper end to within a short distance of the top of thetank, as plainly shown in the drawing. The lower end of the pipe Bpasses through the bottom of the tank and connects in the usual mannerwith the device to be flushed. v

On the pipe B within the tank A is fitted to slide the lower end C of avalve body C made hollow, as plainly shown in the drawing, the upper endof the said valve being connected with the usual lever mechanism 1), orother device for raising and lowering the valve whenever it is desiredto flush the device on which the improvementis applied. From the upperend of the valve body C leads a vent pipe E extending downward on theoutside of the said body to within a suitable distance ot the lower endthereof, as indicated in the drawing. In the lower end of the valve bodyC are arranged inlet openings C through which the water cau pass fromthe tank A to fill the interior of the valve body 0. Now, it

will be seen that when the water in the tank rises in'the valve body Cabove the upper end of the pipe B, then the surplus water can pass intothe said pipe B and down into the bowl or other device. to be flushed,the said pipe B then serving as an overflow pipe. Normally, however, thelevel of the water in the tank A is below the upper end of the pipe 13on the water line indicated in the drawing. Now, when the valve body Cis drawn upward by the manipulating device D, then the water containedin the valve body C is caused to flow into the upper end of the pipe B,so as to form a siphon, the water being thus drawn from thetauk into thepipe B to finsh the bowl or other device with which the said pipe isconnected. The valve body C is drawn usually, into the position shown indotted lines in the drawing, for the purpose of siphoning the contentsof the tank, as above described. Now, when the water has fallen in thetank until the lower end of the pipe E is uncovered, then the siphonaction is broken,

as air can now pass through the said pipe E into the upper end of thevalve body 0. The flow of the water from the tank A into the pipe B thenceases.

It will beseen that by therconstruction described, the valve is renderedcomparatively noiseless, is very simple and durable-in construction, andcan-be readily applied on all kinds of water tanks for flushing or otherpurposes'.

Having thus'fully described my invention, I claim as new and desire tosecure by Letters Patent- The combination with the outlet pipe, of thehollow valve body closed at its upper end and having a downwardlytapering lower end fitting the said pipe as shown at C and thereprovided with lateral i'nlet openings 0*, and

the pipe E leading from the top of the said valve body down along theouter side thereof and terminating a suitable distance above theopenings C substantially as described.
